my car passed smog in cali, here is what i had.
b16a2, skunk2 stage1 cams, skunk2 intake mani, bored tb, mugen thin head gasket, aem cai, dc 4-1 header, tanabe cat back, and a vafc (hidden in glove box, this was really the only non smog piece). put 171hp to the front wheels that way.
EDIT:
and yes, i was ref'd, they give you a cute little BAR sticker for your door jam.
